ACS Honors Josephson, Penfold Donald V. Josephson

A x effort of many years, directed -**- toward making the products of the cow more attractive to the consumer, is now resulting in a prize for Donald V. Josephson, head of the department of dairy husbandry at Pennsylvania State University. For adding contented consumers to contented cows, Joseph-son will receive the Borden Award in the Chemistry of Milk, administered by the ACS.

Donald Victor Josephson was born on a farm in Washington County, Minnesota, on March 16, 1911. He re­ceived a B.S. in dairy manufacturing from the University of Minnesota in 1935. For the first three years of his college career Josephson paid his way by working as a hospital orderly at the university hospital. The job paid $30 a month and meant that he had to rise every morning at 2 A.M. This he didn't mind too much, until in his junior year he decided to get married. He then became a milk truck driver at 50 cents an hour. Now he could sleep till 3:30 A.M.!

Josephson was awarded a Dairy In­dustries Supplies Association fellowship for graduate work, and studied at Penn State in 1936. His master's thesis was entitled "The Relation of the Fa t Glo­bule Adsorption Layer to Certain Characteristics of Ice Cream Mixes." After spending over a year in the Bor­den Research Laboratories, he became instructor in dairy manufacturing at Penn State. There he did research and teaching until 1945, and worked on a great variety of problems, all con­nected with the flavor of milk and milk products. His work resulted in a number of fundamental advances in dairy chemistry and practical advances in dairy manufacturing.

Milk Flavor Problems. Most serious flavor problem of market milk and other dairy products is called "oxidized flavor." Much of Josephson's work has been devoted to recognizing its causes and developing procedures for its prevention. An antioxidant-im-pregnated parchment for wrapping butter and a similar paper milk bottle were developed, along with antioxi­dants prepared from cereals. These cereal extracts have now been in com­mercial production for a number of years, and are used in many food prod­ucts. Oxidative deterioration of dry whole milk is delayed considerably by the removal of the phospholipid frac­tion before drying. That is a Josephson

discovery, as is the high heat treatment of pure milk fat (butter oil) in the presence of a small quantity of nonfat milk solids. This process is an anti­oxidant treatment which considerably extends storage life.

As a result of fundamental studies on the "cooked" flavor of heated milk, a very practical procedure for com­bating oxidized flavor in stored dairy products was originated by Josephson and his fellow investigators. They found that sulfhydryl groups, liberated by certain of the milk proteins as a result of heating, are the source of cooked flavor. It was also found that these groups are potent antioxidants which not only protect the milk from oxidized flavor but help to preserve ascorbic acid. I t is now common com­mercial practice to preheat certain dairy products, particularly raw materials for ice cream manufacture, sufficiently to generate sulfhydryl antioxidants which will protect the product from oxidative changes during cold or frozen storage. Thus, storage life has been gready in­creased. The title of Josephson's doc­toral dissertation, presented in 1943, was "The Effect of Heat Treatment and Antioxidants Upon the Keeping Quality of Pure Butterf at.' ,

Another important ofï-flavor of milk is the "sunlight" flavor, which Josephson showed was caused by light of wave­lengths in the vicinity of 5800 to 6200 A. He recommended an amber colored milk bottle which not only prevents development of the flavor, bu t also pro­tects the riboflavin and vitamin C con­tent of the milk from destruction by sunlight. Work by Josephson and his colleagues showed that the "cowy" flavor in milk is caused by acetone passed into the milk by cows afflicted with ketosis. Faulty metabolism in such animals is responsible.

For a number of years, Josephson has been active in developing flavor evalu­ation techniques for the Quartermaster Food and Container Institute and the American Dry Milk Institute. He has also demonstrated the value of flavor evaluation procedures in improving the palatability of ice cream. Palatability and consumer acceptability involve other factors besides flavor, and Joseph-son has investigated a large number of stabilizers for their performance in ice cream. He is mainly responsible for the development of carboxymethyl-cellulose as an ice cream stabilizer.

Another of his developments was a practical procedure for fortifying evapo­rated milk with vitamin C. It was necessary to devise a satisfactory method for eliminating the effect of other reducing substances present in large quantity in evaporated milk, and which otherwise would be determined as ascorbic acid. Investigations into the high heat treatment of milk resulted in the identification of some of the sub­stances produced by such treatment, throwing some light on the chemistry of the flavor changes involved, as well as on the "browning" reaction, familiar to all who have saved sliced fresh apples or peaches too long.

Other Specialt ies. Dairy plant sani­tation, keeping quality of milk, ice cream and dry milk processing, and the ion exchange process for stabilizing evaporated milk toward the heat of sterilization are Josephson's other re­search fields.

He has been an inspiring adviser and teacher of both graduate and under­graduate students. His friends and associates describe him as original and stimulating; working with him, they say, is a pleasure and an education. He is not interested in obtaining patents or achieving personal recognition.

In 1945, Josephson became associate professor in dairy technology at Ohio State University. Penn State recalled him in 1948 to assume his present position as head of the department of dairy husbandry, including dairy manu­facturing, dairy production, and bovine physiology and reproduction. H e reigns over a semicommercial dairy plant, large production establishments for a herd of over 500 animals, and a re­cently completed artificial breeding center and laboratory.

Each summer, Josephson enjoys a "busman's holiday," as he, his wife, and their two sons vacation in a cabin on the family farm in Minnesota.

Despite his heavy administrative burden, he continues to be active in both teaching and research. "An ad­ministrator soon becomes a has-been in his own field, although it is very grati­fying to see the younger men stepping out in your place," he says.

A. R. Penfold A WIDE range of interests and the en-

**' ergy to keep in close touch with all of them are attributes of Australian A. R. Penfold, this year's recipient of the Fritzsche Award, administered by the ACS. Penfold is director of Syd­ney's Museum of Applied Arts and Sci­ences. He is a recognized authority on Australian essential oils and is being honored for pioneering in this field.

JProh>ably the; greatest contribution of Pesnfold and has collaborators was in­troduction of t h e concept of "physio­logical forms" of plants. The concept ha-5 clarified mtuch confusion that pre­viously existed! in trie chemistry of euroalyptus oils. During t he course of ork*e of his m a n y field trips, Penf old ex-anninecl the l eases of several eucalyptus trees. Althougjh the trees were botani-cOly identical—indistinguishable by arny morphological differences—on craishing the leaves between his fingers he* observed tihat the odors of the re­spective oils w e r e different. Distilla­tion of the leaves from the individual trees and chennical examination of the oils confirmed his field organoleptic coenclusion. Tfcius the so-called physio­logical forms of Australian native species were discovered.

Museum achininistration and chemi-ca_l research axe not easily combined, burnt the Sydney museum is one of the fe^v museums in the world having its own laboratories in the buildings. Pen-fold's museum has three functions: ex­hibition, infoiraation, and research. Tine work of the botanical and the cfftemical laboratories is an important aspect of the museum's program and an aspect in w h i c h Penfold has a strong personal interest . Assigned to chemical research there are five senior and three jumior chemisfis. "I wouldn ' t want a laarger staff," s^ys Penfold. He likes to b e in close t o u c h with all important work "being d o n e by subordinates.

His distillery is equipped with all types of batcL· stills; they range from a small glass u n i t holding a pound of fo*liage up to a large iron still taking a 2000-pound claarge. Init ial distillations acre done in thiese batch stills and final oil fractionations in laboratory columns.

Influenced Eucalyptus Oil Indus t ry . Iovestigations of oils from Australian flora "by the museum has resulted in thae establ ishment of the eucalyptus oil iradustry in Australia and laid the foun­dations for synthetic thymol and men­thol p roduc t ion from eucalyptus oil.

Penfold h a s a keen interest in horti-cmlture. Al though it really is a hobby, it has always: been closely related to h is work. In fciis own private garden he developed several important oil-pro-cbucing species of eucalyptus. It is be­lieved that t l i e fruitful results of his home gardening influenced the New Skwth. Wales government to establish rifcvo exper imenta l plantations to carry om this type of work.

Penfold wil l receive the Fritzsche Akvvarcl in Kansas City next week. This will b e his t t i i rd trip to the U . S. H e fiixst visited tn i s country in 1939 under a. Carnegie g ran t , made t o enable him t o collect information on museum pres­entation and construction. H e visited

.major museums not only in this coun­try, bu t also in Canada and in the principal countries of Europe. He returned to the U. S. in 1954 as leader of the New South Wales government mission on plastics and synthetic fibers.

Penfold has served as president of the Royal Society of New South Wales and Foundat ion Chairman of the Aus­tralian Section of the Oil and Colour Chemists' Association. H e has received the Henry G. Smith Medal of the Australian Chemical Institute for out­standing contributions to thé chemistry of Australian plant products and the Royal Society of New South Wales Medal for research on chemistry of es­sential oils carried out during the past 30 years.

A. R. Penfold was born in 1890. He was educa ted in the state public schools a t Sydney, and the Sydney Technical

College. He graduated from the Tech­nical College in 1914 after studying a combined chemistry, physics, and bot­any course. After four years in indus­try as a research chemist with an essen­tial oil distiller he was appointed as­sistant economic chemist with the Sydney Technological Museum (now called the Museum of Applied Arts and Sciences), and has been its head since 1927.

Penfold and his wife are now in London on what he calls a half busi­ness and half pleasure assignment. It is business because he is undertaking several important missions for his gov­ernment. I t is pleasure because they have plans for several European holi­day trips, and then, too, his daughter, Dulcie, is now working in London. The Penfolds plan to return to Aus­tralia in August.

Chandler Medal Presented to Willard Frank Lib by Willard Frank Libby, professor of chemistry in the Institute for Nuclear Studies at the University of Chicago, receives Columbia University's first Chandler Medal for the Bicentennial year of 1954, given for outstanding achievements in the field of chemistry. Dr. Libby is widely known as the originator of the carbon-14 dating technique, a method for accurately determining the age of organic material as much as 25,000 years old. The technique is used by botanists, geologists, archeologists, biolo­gists, and others to determine age of ancient animal and vegetable remains. Left to right: Edward C.

General Mills Provides Amine Source >nv^ Resin Blends Show Coating Benefits ̂ i^wviir Aliphats Cut Buffing Compound Cost

Fatty Amine Users are now offered a new source of continuous amine supply by General Mills.

General Mills has fatty amines for either direct use or for further processing . . . readily available in drum or carload lots. These amines are processed at the General Mills chemical plant in Kankakee, Illinois, where con­stant quality and uniformity are guaranteed by high-standard automatically controlled processes.

A reliable, well-estab­lished firm with the best of technical personnel. . . plus top research and production facilities . . . General Mills produces a variety of Ala-mines (fatty amines), Ala-macs (fatty amine acetates), and Alitriles (fatty nitriles).

For further information on General Mil l s F a t t y Amines, please mail the coupon below.

D e c o r a t i v e and Protective Coatings got a new boost when Polyamide and epoxy resins were blended recently. These t h e r m o s e t t i n g b l e n d s proved excellent for coating collapsible metal tubes, foil, paper, machinery, masonry or concrete, and for other important applications.

Polyamide-epoxy resin coatings display an unusual combination of adhesion, flexibility, hardness and impact resistance. They are high-gloss coatings with excellent chemical resistance to both alkali and acid.

You can apply these new coatings by spray, dip, roller-coat or brush methods, and can either air dry or bake them. However, you get approximately a baked-enamel finish by merely air drying at room temperature. They "dry rapidly to handle," and may be recoated in a few hours. These coatings cure primarily without oxidation, so thicker films may be applied.

General Mills recommends either Polyamide Resin 100 or 115 for these coating blends with epoxy resins. Poly-amide Resin 100 has superior resistance to acids while Polyamide Resin 115 has superior resistance to solvents. Both are outstanding in alkali resistance and flexibility. They are the latest developments in a rapidly advancing field. For more information, mail the coupon.

All Buffing Compound Manufacturers want to lower raw material costs. That's why General Mills offers a variety of products which may be used economically in buffing compounds—all closely controlled to insure con­stant uniformity.

The chemist at work on the vacuum coating unit and electron microscope, above, illustrates the research that accounts in part for General Mills' rapid success as a chemical supplier.

For example, greatly reduced costs may be obtained by using General Mills Vegetable Oil Pitches to extend your fatty acids. We suggest you try blends of pitch with Aliphats 7-C or 7-R (hydrogenated tallow acids) or Soap Acids No. 4 (a low cost high palmitic acid product). Aliphats 7-C and 7-R are also used readily as substitutes, in whole or part, for hydrogenated marine fatty acids.

Or, try General Mills Aliphat (fatty acid) 6-A, a special mixture of palmitic and stearic acids. This i s a non-crystalline type, par­ticularly suited for all ap­plications where a tough, hard, waxy buffing com­pound is desired. Aliphat 6-A offers good shrinkage without cracking when melted and cooled.

On the other hand, the specially processed, frac­tionally distilled saturated fatty acid, Aliphat 6-BW (comparable to triple press­ed commercial stearic acid) shows little shrinkage when melted and resolidified. Less costly Aliphat 6-C, with saturated acid ratio of approximately 60% pal­mitic and 40 % stearic acid, has good stability and wili perform effectively and eco­

nomically where the lighter color of double and triple pressed types is not required.

General Mills manufactures these and other fatty acids for buffing compounds. If you would like additional in­formation, please mail the coupon below.

There is an ALIPHAT for your specific need.
